Subject: [PATCH 01/11] hw/mips/loongson3_virt: Factor generic_cpu_reset() out
Date: Sun, 12 Jan 2025 22:58:25 +0100 [thread overview]
Message-ID: <20250112215835.29320-2-philmd@linaro.org> (raw)
In-Reply-To: <20250112215835.29320-1-philmd@linaro.org>
main_cpu_reset() is misleadingly named "main": it resets
all vCPUs, with a special case for the first vCPU.
Factor generic_cpu_reset() out of main_cpu_reset(),
allowing to remove one &first_cpu use.
